Minami Natsume, the primary songwriter for idol group ŹOOĻ, is 19 years old, standing 174 cm tall and weighing 58 kg with blood type AB. Born on June 8, he enjoys eating and playing piano but harbors a dislike for crowds and rabbits—the latter stemming from a childhood bite. His hobbies include collecting watches and clocks, and he is ambidextrous, often drinking with his left hand.

A former child acting prodigy, Minami faced intense maternal pressure to prioritize acting over music, leading him to abandon piano lessons and forgo a contest despite early enthusiasm. While studying abroad in Northmare, he met Haruki Sakura, whose support solidified his songwriting ambitions. Their partnership fractured over disagreements regarding Haruki's health, which Minami blamed on IDOLiSH7's Nagi Rokuya, contributing to complex industry relationships.

Outwardly composed and gentle with a polite tone, Minami's words frequently carry intentional malice. He utilizes fortune-telling to analyze others' personalities. His surname "Natsume" (棗) references a tea ceremony container, while his given name "Minami" (巳波) combines "snake/serpent" (巳) and "waves/breakers" (波), reflecting his layered nature.

Within the concert film *LIVE 4bit BEYOND THE PERiOD*, Minami performs as part of ŹOOĻ alongside IDOLiSH7, TRIGGER, and Re:vale. The film features joint concerts across two days with varied setlists, emphasizing stage performances and ad-libbed interactions, highlighting Minami's identity as a ŹOOĻ performer and songwriter navigating industry challenges.

Shaped by familial pressure and professional conflict, Minami exhibits a calculated, occasionally antagonistic approach to his career. He maintains a surname-based dynamic with fellow ŹOOĻ member Haruka Isumi, who addresses him as "Minami."
